The method for the recursive calculation of the effective potential is applied successfully in case of weak-coupling limit (g0) to a multidimensional complex cubic potential. In strong-coupling limit (g), the result is resumed using the variational perturbation theory (VPT). It is found that the convergence of VPT results approaches those expected.
